Abstract Details

Purpose:

To evaluate the postoperative change in anterior chamber depth (ACD), keratometry values and central cornea thickness (CCT) in patients with mature cataract.

Setting:

Kafkas University Faculty of Medicine, Ophthalmology Department

Methods:

In this prospective study 18 eyes of 18 patients (5 women and 13 men) with mature cataract (study group) and 32 eyes of 31 patients (10 women and 21 men) with non-mature cataract (nuclear, posterior subcapsular, or cortical) (control group) who underwent phacoemulsification and intraocular lens implantation were evaluated. Preoperative ACD, keratometry values and CCT were measured with topography (Sirius, CSO, Florence, Italy) and optical biometry (Nidek, Aichi, Japan). These parameters were measured one week, one and three months after surgery. Patients with mature cataract were compared with those with non-mature cataract in terms of postoperative changes.

Results:

Preoperative mean ACD was 2.56±0.40mm in the study group and 2.85±0.38mm in the control group(p=0.02). In study group, although there was a significant increase in ACD in the first month compared to the first week, the change between first month and third month was not significant (p=0.03, and p=0.55,respectively). In the control group, there was no significant difference in ACD in the first and third months compared to the first week (p>0.05). Although CCT stabilized later (one month versus one week) than the keratometry in both groups, there was no significant difference between groups in terms of stabilization duration (p>0.05).

Conclusions:

ACD, which is one of the most important factors affecting the effective lens position, becomes stable in the postoperative first week in non-mature cataracts and in the first month in mature cataracts. Phacoemulsification induces more significant ACD changes in patients with mature cataract compared to patients with non-mature cataract. However, the flat and steep keratometry and CCT stabilization did not differ significantly between the groups. Although keratometry values stabilize in the first week in both groups, it may take up to one month for the CCT to stabilize.
